BEARING FOR .SPINDLES.

SPECIFICATION forming part of Letters Patent No. 285,461, datedSeptember 25, 1883.

Application filed March 9, 1883. (No model.)

To an whom it may concern.-

Be it known that we, CHARLES G. BUTTRIOK and TIMOTHY B. FLANDERS, bothof Holyoke, in the county of Hampden and State of Massachusetts, haveinvented a new and useful Improvement in Bearings for Spindles, of whichthe following is a specification and description.

The object of our invention is to lock the bearing for the spindle, toprevent its turning in the same direction in which the spindle is turnedin the operation of spinning, by the Fig. I, the section being taken online Aof that figure.

In the drawings, 2 represents the upper rail,

. and the lower rail, of aspinning-frame having the usual vertical holesmade therein to receive the ordinary spindle-bolster and step. Intothese holes in the upper rail we insert the bearing-case 3, with,preferably, an exterior shoulder, i, thereon resting upon the rail, andthis case has a vertical hole extending through it, which is of smallerdiameter at 10, with an interior shoulder, 5, located horizontally nearone end, and whose opposite end has aninterior screw-thread madetherein, adapted to receive a threaded nut, 8, fhaving a vertical holetherein, and a vertical shoulder or lug, 13, made on its extreme upperend. The bearing 12 for the upper rail is substantially a tube, providednear one end with an exterior shoulder, 6, also located horizontally tofit well against the interior shoulder, 5, of the case, and the upperend of this hearing is made to fit the hole in the case above theshoulder 5 somewhat loosely, and the lower end of the bearing is made tofit the hole in the nut 8 somewhat loosely also, as shown in Fig. II.The bore of the case 3, below the interior shoulder, 5, is of sufiicientsize to receive a spiral spring, 7, placed around the exterior of thebearing 12, which spring is of sufficient length that when the nut 8 isturned into place in the end of the case the spring will be compressedsomewhat between the horizontal shoulder 6 on the bearing and the end ofthe nut, and when the spring is in place within the case 3 and aroundthe bearing 12 the upper extreme end of the spring abuts laterallyagainst the vertical shoulder 13, made, on the lower side of thehorizontal shoulder 6 of the bearing, and the lower extreme end of thespring abuts laterally in the opposite direction against the lowervertical shoulder, 13, made on the upper end of the nut 8, as shownclearly at D in Fig. II. This bearing also serves the purpose of a stepfor a spindle, as well as an upper bearing, by leaving the nut 8 wholeat the lower end, as shown clearly in the lower part of Fig. II at D andE. For the step we preferably make the case quite short, with its lowerend to rest upon the lower rail, 20, and

make the nut sufficiently long toextend up through the rail and turninto the lower end of the case, and make the hole in the nutfrom theupper end sufficiently large and deep to receive thebearing 12 andspring 7, with a horizontal shoulder near the bottom of the hole in thenut for the spring 7 to bear down upon, and also a vertical shoulder orlug, 13, projecting up from this horizontal shoulder, against which theextreme lower end of the spring may impinge laterally to prevent thelatter from revolving in one direction. The nut is bored out, of smallerdiameter in the bottom, to. provide a space therein below the lower endof the bearing 12 when used for a step, so that the bearing may have afree movement in the nut.

The hole in the bearing 12, when used for the step, instead of extendingentirely through the bearing, may only extend "in from the topsufficiently to receive the lower end of the spindle, as shown clearlyin the lower part of Fig. II, at 18, inE.

I To insert the bearings and spindles in place,

bearing 12 is inserted into the case, with the shoulder 6 of the bearingagainst the shoulder 5 of the case. The spiral spring 7 is placed uponthe bearing 12, and the nut is turned into place in the end of the case.When the de the nut 8 being turned out of the case, the

vice is in place in the rail it is held secure therein and madestationary by any convenient means, preferably by a set-screw, 17,turned into the rail and against the case. The

. spiral spring 7 is wound in an opposite direction from that in whichthe spindle revolves, so that if the bearing 12 is inclined to revolveby the friction of the spindle revolving therein, the upper verticalshoulder 18 impinges against the extreme upper end of the spring 7, andas the extreme lower end of the spring impinges against the lowervertical shoulder 13 of the nut, and as the case is held stationary inthe rail, the bearing 12 is thereby prevented from revolving. If thespindle is to be used for twisting, or is to revolve in the oppositedirection, the spring 7 should be wound the other way, so that itsextreme ends will abut against the opposite sides of the verticalshoulders 13.

It will be seen that when constructed as above described the spindle andits bearing will have all the advantages of an elastic or yieldingsupport in all directions, and yet the bearing will always be heldstationary by an elastic force applied to the bearing, so that thelatter may not revolve with the spindle in the operation of spinning.

Lubricating-oil may be applied to the spindle above the bearing 12, and,if desired, an oilhole may be made through the bearing 12 and inside thecase, as at 25, to permit the oil as it works down the spindle to passoutward into the spring, and as the coils are somewhat close together,the oil collects in the spring, es pecially while the spindle is notrunning, and when the spindle begins to get warm again byits friction inrunning, the oil is again drawn out of the coils of the spring, so thatthe latter serves to hold the oil as a reservoir, from which a supply isoccasionally drawn.

It is evident that instead of a projecting vertical shoulder or lug, 13,made on the hearing and on the top of the nut 8, a notch having avertical side may be made in the horizontal shoulder 6, and another inthe top of the nut to receive the lateral thrust of the end of thespring, and serve the same purpose 5 but we prefer the lugs cast thereonas being more easily made.

This bearing is cheaply made, is effective, and for some purposesas, forexample, a spinning-frame with a single railit may be reversed in itsposition, so that the nut 8 may be uppermost and operate in preciselythe same manner and without departing from the invention in the least.

Having thus described our invention, what we claim as new is Thecombination of a case, 3, having an internal shoulder, 5, a bearing, 12,provided with an external shoulder, 6, and a vertical shoulder, 13, anut, 8, adapted to be secured in the end of said case, and provided witha similar vertical shoulder, 13, and a spiral. spring, 7, to be insertedwithin said case and around said bearing, whereby the said bearing isrendered movable and yielding in its position, and is also held fromrevolving with the spindle by the pressure of said spring against saidshoulders, substantially as described.
